6. A certain convex lens is used to create an image of an object that is 2.0 m in front of the lens on a white screen that is 15.0 cm behind the lens. For the sake of clarity in the description that follows, assume that the object, lens, and screen are on the x axis, the lens sits at the origin, and the object is in the positive x direction (so...
An object is placed in front of a minor and an image is produced on a screen which has a magnification of -2.85 when the screen is placed 33.0 cm from the mirror. What type of mirror is being used? If the original object is erect and 14 cm tall, how tall is the image on the screen? What is the focal length of the mirror? If the screen is moved to 35 cm away from the mirror, how far...
When two lenses are used in combination, the first one forms an image that then serves as the object for the second lens. The magnification of the combination is the ratio of the height of the final image to the height of the object. A 2.00 cm -tall object is 57.0 cm to the left of a converging lens of focal length 40.0 cm . A second converging lens, this one having a focal length of 60.0 cm , is...
When two lenses are used in combination, the first one forms an image that then serves as the object for the second lens. The magnification of the combination is the ratio of the height of the final image to the height of the object. A 1.70-cm-tall object is 55.0 cm to the left of a converging lens of focal length 40.0 cm. A second converging lens, this one having a focal length of 60.0 cm, is located 300 cm to...

When two lenses are used in combination, the first one forms an image that then serves as the object for the second lens. The magnification of the combination is the ratio of the height of the final image to the height of the object. A 1.20-cm-tall object is 50.0 cm to the left of a lens of focal length of magnitude 40.0 cm. A second lens, this one having a focal length of magnitude 60.0 cm, is located 300.0 cm...

A converging lens (f = 26.1 cm) is used to project an image of an object onto a screen. The object and the screen are 114 cm apart, and between them the lens can be placed at either of two locations. Find the two object distances. (Enter your answers from smallest to largest.) cm cm
